At just under one week old, Swift is already fourth when it comes to forks (2,361). Only Rust (2,822), PHP (2,752) and Ruby (2,599) have more.

It’s only one metric, but GitHub is the go-to source for open source language development, so it’s a good one. GitHub’s list lacks heavyweights like C++ or Java, for instance, but in being where developers spend much of their time, I think Swift stands a good chance of topping any language popularity list in the near future.
